CONVERTIBLE CHAIR.

SPECIFICATION forming part of Letters Patent No. 325,999, dated September 8, 1885. Application filed Julylft, 1884. (No model.)

delphia and State of Pennsylvania, have in-' vented certain new and useful Improvements the form of a childs high chair.

in Convertible Chairs, of which the following is aspecification, reference being had therein to the accompanying drawings, wherein Figure 1 is a perspective of my invention in Fig. 2 is a like view illustrating the descent of the chair in its supporting-frame to form a low chair. Fig. 3 is a vertical section of Fig. 1 through the line 1 1. Fig. 4 is a rear view of the chair seat or frame partly broken away. Fig. 5 is asection view of the swiveled guides for the chair. Fig. 6 is a perspective of the rocking form of chair, and Fig. 7 is an elcva= tion of the roller or chariot form of same.

My invention has relation to convertible chairs for children, or that form of the same which can be changed from a high to a low rocking and roller or chariot chair;and it has for its object to provide a simple and inexpensive convertible chair, the parts of which are so constructed and arranged that the different changes of form or position can be easily and quickly effected.

My invention accordingly consists of the combination, construction, and arrangement of parts,as hereinafter described and claimed, having reference particularly to the provision of a supporting frame or platform the sides of which have rear concave or segmental bars and front bars with convex or rocking edges, and a chair having supporting-hooks and swiveled side guide-pieces which engage with the rear concave bars of the sides of the frame or platform.

In the drawings,(A represents the platform or support for the chair seat or frame B, and which is composed of two parallel sides, 0 O, united by a top and two bottom cross-bars, c and 0, respectively. The sides 0 O are each made up of a front bar, d, having outer convex or rocking edge, d, and a segmental or concave rear bar, at", joined or otherwise connected at their upper parts, as indicated at d If desired, the bars 01 and d of the sides 0 O are connected near their lower ends by side bars, D D.

I The chair B may be of any desired construction. and design, having a seat, b, with or without pot-opening b. If such opening be used,a hinged seat or lid, E,is secured to seat b, as shown. The chair B is also provided with arms f and a foot'rest, g.

On the rear side of the chair,on its back and at the top of the same, are fastened hooks G, or like devices, which 'pass around the crossbars 0'0 and hold or support the chair in its adjusted or converted position. 7

To the'sides of the chair-seat b, at its rear end, are fastened swiveled guides or flanged plates H, the sides or flanges h whereof embrace and move up and down upon the bars 03 as the chair is converted from one position to another, the construction of said guides and the screws for swiveling them to the chair-seat being plainly shown in Fig. 5.

To the chair-arms f is hinged a table, I, or it may be connected to the frame A, as indicated by dotted lines a in Fig. 1.

When the frame A is in the position shown in last-named figure, and the chair-hooks G are connected to the top crossbar, c, as illustrated, ahigh chair is formed, the lower part of the chair B being then supported or steadied by the flanges h of guides H.

By disconnecting the hooks G from the cross-bar c and lowering the chair B, as represented in Fig. 2, until its foot-rest g meets and rests upon the front cross-bar '0, a lowdown chair is provided. In this case said bar 0 supports the weight of the chair B, and its upper part is then steadied by the guides H.

By turning the frame A down upon its rocking edges (2 and slightly raising the chair B and oscillating or turning it on the -swiv-' eled connections of the guides H until its footrest 9 meets and impinges upon the crossbar '0 a rocking-chair is formed, as show in Fig. 6.

If the bars d be provided with rollers, as represented at m, Fig. 3, and the frame A turned down, as shown in Fig. 7, a roller or chariot chair is produced, in which case the frame of the chair B and its weight are supported by the guides H or their side flanges.

It will be noted from the foregoing that the guides H not only direct the path of travel for ICO the chair B, but they also, by reason of their flanges h, steady andassist in supporting said chair on the frame A. These guides H, however, instead of having flanges for embracing bars dflmay be a plain plate or guide and enter and move in appropriately-shapcd slots in bars.

\Vhat I claim is- 1. A convertible chair-frame, A, comprising sides G G, composed of rear concave or segmental bars, (1", front bars, (I, having outer convex or rocking edges (1 and connecting cross-bars c c, in combination with an adjustable chair, B, having hooks G and swiveled side guides, H, substantially as shown and described.

2. In a convertible chair, the combination of chair-frame A, having rear side barsalfland connecting crossbars c 0, and a chair, 13,
